'l'o alt whom it may concern:

Bc it known that T, Enwaiui C. Swn'i'r, a

citizen of the United States, residing at lieloit. in the county of Rock and State of Wiscousin, have invented certain new and useful Tin iroreincnts in Liquid-Gages for Tanks;

an( I do hercbv declaro the followin tolieI a full, clear, an( exact description o .thc in vcntion, such as will enable others skilled in the art to which it appertaiiis to inakc and use thc saine, reference liciiig had to the accompanying drawings, and to the letters and figures of reference niarkerl thereon, which forni a part of this specification.

This invention relates to new and use ful improvements in liquid gages for tanks in which an intermittent` rotary inoi'cuicnt is ada ited to be iinparted to n shaft carrying My invention coniprises various details' lot' construction and combinations and arrangements of parts which will he hereinafter fnllydcscrilicd and then specifically detiiied in the appended claims.

I illustrate my invention in thc aeeom pnnying drawings, lin which Figiire 1 is a sectional view througha casing showing the electro-magnet an contact arms in elevation. Fig. 2 is n cross sectional view through the casing showing in top plan 'view the p'aits illustrated in Fig. l ot thc drawings, inoliilc .showing tht` application of the invention thereto. l"ig. -l is a side elevation ot :i dial and indicating pointer inoi'ahle adjacent thereto. l"ig. :'i is a sectional view f through the tank showing the Iloiit and the f contact points coi'iperating with the loiit to close circuits. and lt`ig. t' is a longitndiiial L .sect ion at right angles to that shown in Fig. t. Fig. 'i' is a detiiil view of a spring and a link actuated therehy toruiing a part. of the invention.

ltel'erencc now heing had to the details of the drawings hy lcttet'. designates a cas- Fig. .'t is an elevation ol' an auto-l iiig which iiiay he of any size and shape and supported hy tht` staiidiird A' and con- .tained within said casing is a series ot' clectro-magnets, designated hy letters ll, C, l) it, to receive thc rod upon which it is vuidcil `and ll. Mounted in suitahle hearings in thi` walls of the casing is a rotatahlc shaft l" upon which a coiled spring l"' is inouutcd, one end heing tixcd to the. easing and the. olliei' eiid tothe shaft. thc purpose otl which spring is tn norinalliI retiuii the shaft to its starting position at'tcihavingheen given a rotary nioi'enieiit sutlicieiit to indicate iiiiy height ot' liqiiidwithin tlictank. Fixed to said shaft are the disks (`i`r,ll,l and l\',an l J designates pins projecting troni correspond ing faces of the disks and spaced apart. A series of links N is nionnted upon the pins 1"' which project from each disk and to each link is pirotally connected, hy nicaiis of a pin t). a second link O and a spring O is provided for the purpose ot normally holdin solid lines in Fig. 1 of the drawings.

Upon reference to Figs. 1 and 2 of the arriuiged in alternate relation one to anothci' ain iiectcd ti'e of the links N each link upon. cach disk designating one of thc sub-d- \isioiis of the dial Q which shows iiuineials troni zero to 10,.'i suitable indicating pointer li. which is fastened to the shaft. l, serving to register adjacent to thc dial. said dial tie .ing coi'ercd hy a glass Q.

Projecting t'roni the disk G is a pin G' which is longer than the other pins thereon tand is iidiipted to cot'iperate with the hooked A.end ot' the resilient liar l. to liinit the return jiiioienient of the shaft. and prevent'. a fur ther rotary uioi'enientl when the indicator lrctiirns to zero. Underneath the series of disks is a concaved .shield Sagainst which ltlic outer t'recq ends of the links O arc' ladaptcd to project. as the shaft rotates and 5 fatter the links t) tilt nt tlicii pivotal joints l ias one contact after another with the electro* i iinagnet lircaks. and Sis a brace rising froin i .'tla` hottoin of thc casing A and engagingj the shield S.

ltctcirinff to Figs. ."i and t ot the drawings there will ie seen a tank 'l adapted to contain the fuel having an opening closed hy incans of the plu 'l". Fixed to said plugr are the two tnlics l" and 'l` which arc parallel to cach other and spaced apart. a slight distance.

'lhc second tuhe l` iilso has a series ot' contact points 'l". each ot which has a wire. 'l" connected thereto cach wire hcing adapted to he connected to one f ot' said clectio-iiiagncts. rod 'l" is also fastened to the plug 'l"'and is positioned inj tcriiiediate the tnlies 'l`2 and 'l and a tloat. 'l" is provided which is centrally apertured f as it rises and falls with the liipiid nel W within the tank. Said tloiit 'l`". itl will he noted. is of such a length as to always inakc contact with two pairs ot' the contartpoints` ln operation` it. will be noted that two ot' as it rises and t'alls within the tank.
